Ginger is a realistic portrayal of what a spoiled but not too arrogant noble lady would be. She's kinda selfish, but she does have empathy for others. She isn't the goody goody dense villainess that has become common in Japanese ones, but she isn't a perfect cold genius villainess out for murderous revenge either.
In other words, she is very relatable because she is just a normal girl anyone can relate to.
